You shall also decree a thing, and it shall be established for you: and the light shall shine upon your ways.
Light is sown for the righteous, and gladness for the upright in heart.
Unto the upright there arises light in the darkness: he is gracious, and full of compassion, and righteous.
But the path of the just is as the shining light, that shines more and more unto the perfect day.
Then shall your light break forth as the morning, and your health shall spring forth speedily: and your righteousness shall go before you; the glory of the LORD shall be your rear guard.
Your sun shall no more go down; neither shall your moon withdraw itself: for the LORD shall be your everlasting light, and the days of your mourning shall be ended.
Then spoke Jesus again unto them, saying, I am the light of the world: he that follows me shall not walk in darkness, but shall have the light of life.
1 John 2:10
He that loves his brother abides in the light, and there is no occasion of stumbling in him.
